I'm doing it. Tips having done it before. * Run hardly if at all in the last week. Taper madness will make you feel you should: ignore it. And Taper madness will make you feel like you're injured when you're probably not. * Do not eat too much the night before. And not much fibre unless you want the world to fall out your bottom. * Go to the expo before the out of towners arrive - so ideally Wednesday or Thursday. Do not leave it until Saturday afternoon. Take your passport/driving licence. And don't waste money on the Pasta Party * Pin your number on well: if you lose it or it falls off you will not be allowed to complete the race. * When on Blackheath/Greenwich, queue for the toilets early and once you've been join the queue again. * Take loo roll with you. The stuff in the portaloos is like sandpaper and that's if there's anything left * If people are coming to watch you, make sure you know where they are. The crowds are huge. Tell them to avoid areas such as Greenwich, London Bridge, Canary Wharf and the embankment. Crowds are five deep there. I'd recommend Surrey Quays/Jamaica Road and between Limehouse and Blackfriars. * Do not assume the crowd will get you round. There are grim bits on the course: Limehouse to Blackfriars is like a war zone. Prepare for the mental strain as well as the physical. * Apply Vaseline to your feet and amply to any chaffable areas. * The road cambers can kill you. Stay on the crown of the road and don't move from side to side. You'll end up doing over the 26.2 * If you're no athlete (like me) allow yourself the option of the odd walk. A couple of minutes through the Lucozade sport stations won't alter your overall time and might even improve it. * Don't overdrink. The last person to die on the course (2oo7) died because he drank too much. Oh and enjoy the day!
